ZCoin (XZC)

Zcoin's two main pillars are privacy and decentralization. Its Zerocoin anonymization method is built into it at a protocol level and uses proven cryptography that allows users to wipe transaction history from a coin while retaining supply auditability. Unlike other privacy mechanisms which merely obfuscate the trail, the Zerocoin protocol allows complete breakage of the transaction trail while remaining auditable.Zcoin also has a working prototype of MTP, a new proof of work algorithm that is meant to be truly ASIC resistant by requiring huge memory requirements on the miners while remaining lightweight on the verifiers. MTP is scheduled to launch in 2018. The project aims to bring back the true vision of what Bitcoin was supposed to be, private, fungible and decentralized.
